The processing module 23 can determine whether the state of the door body 112 is open or closed according to the detection result of the door opening and closing detector 121. When the processing module 23 determines that the door body 112 has not been opened according to the door opening and closing history data for more than the preset time length (for example, 48 hours or 72 hours, etc.), it is determined according to the light sensing history data and the brightness abnormality judgment principle. The brightness of the ambient light of the refrigerator body 11 is abnormal. The processing module 23 transmits the abnormality notification to the portable electronic device 3 via the network communication module 21 and the communication network 200. The control circuit 34 of the portable electronic device 3 receives the abnormality notification via the communication unit 31, and outputs the abnormality notification via the display unit 32. Therefore, the user 400 of the portable electronic device 3 can notify the abnormality of the use state of the refrigerator 1 through the abnormality notification, and can immediately contact or view the user 1 of the refrigerator 1 to confirm the health status and activities of the user 300. status.

In summary, the refrigerator usage state detecting system 100 of the present invention analyzes the detection result of the door opening and closing detector 121 and the sensing of the light sensing unit 124 by the server 2 As a result, when the detection result of the door opening and closing detector 121 represents that the door body 112 has not been opened for more than the preset time length, the abnormality notification is transmitted to the portable electronic device 3, thereby allowing the user of the portable electronic device 3 The 400 is notified by the abnormality that the use state of the refrigerator 1 is abnormal, and the user 1 of the refrigerator 1 can be immediately contacted or checked to confirm the health status and the active state, so that the object of the present invention can be achieved.
